L1 Phase Indicator (3)
Indicator showing the correct assignment of L1 and N to the measurement chan-
nels. LED "L1" lights up if the polarity of the mains plug is correct. See also
Chap-
ter 4.3, "Connecting to Power" , on page 16.
ON LED (4)
This LED shows that the R&S ENV216 is powered up.
Remote LED (5)
This LED shows that a remote control function is active. See also Chapter 5,
"Remote Control" , on page 26.
This LED goes off automatically when all remote control functions are inactive or
the port is not occupied.
L1, N (6), (7)
The measurement path is selected manually using the "L1" and "N" keys. When
either key is pressed, it releases the other. They are both locked when the
"Remote" LED is lit. The associated LEDs always indicate the active path, even
when this has been selected using the remote control. See also
Chapter 5,
"Remote Control" , on page 26.
150 kHz HP (8)
With this toggle key a 150 kHz highpass filter can be switched into the measure-
ment path. This enables interference voltages in the low-frequency range, e.g.
from switch-mode power supplies, to be suppressed. The associated LED lights
up when the filter is active. This key is locked when the "Remote" LED is lit. See
also
Chapter 5, "Remote Control" , on page 26
Limiter (9)
With this toggle key "Limiter" the internal protection diodes at the measurement
output "RF Output" can be turned off. The protection diodes act as an input volt-
age limiter (transient limiter) attached before the "RF Output" output to protect
measurement equipment from high positive and negative voltage spikes (>6 V).
By turning off the protection diodes higher interference voltages can be mea-
sured.
The "Limiter ON" LED lights up when the protection diodes are active.
The default setting, e.g. after switching on, is "ON".
The limiter function is only locally switchable by the toggle key "Limiter".
